I’m trying to migrate a JavaX.mail class to use Jakarta mail, as it’s required to move from Tomcat 9 to 10. I’m receiving a message java.lang.IllegalStateException: Not provider of jakarta.mail.util.StreamProvider was found when attempting to send emails via gmail.

I have included angus mail in the .classpath file, as well as the jakarta mail and activation

<classpathentry kind="lib" path="/home/astump/src/codex/Java/asWeb/web/WEB-INF/lib/angus-mail-2.0.3.jar"/>
<classpathentry kind="lib" path="/home/astump/src/codex/Java/asWeb/web/WEB-INF/lib/jakarta.activation-api-2.1.3.jar"/>
<classpathentry kind="lib" path="/home/astump/src/codex/Java/asWeb/web/WEB-INF/lib/jakarta.jakartaee-api-10.0.0.jar"/>

However, this is not resolving the issue.
